spring和rabbitmq整合，会概率性的出现取不到数据的情况

Question

向队列里放入数据的语句：this.amqpTemplate.convertAndSend("queue_one_key", xml);

 从队列里取数据的类：@Service(value="MessFromMq")
public class MessFromMq implements MessageListener {@Override
    public void onMessage(Message arg0) {String message = "";//取出的报文
        try {
            message = new String(arg0.getBody(), "UTF-8");
        }catch (UnsupportedEncodingException e) {
            this.log.info(e.getMessage(), e);
            return;
        }}}

其中arg0是从队列里取出的数据
spring-mq的配置文件：
